Most battles won have been won because of being equipped with the proper weaponry. Though the substance may be different in Christian warfare, the same theme prevails. No believer is nearly as successful in battle as he is when he dons “the whole armour of God” (Ephesians 6:11). This armour assists the believer as he seeks to stand “against the wiles of the devil” (Ephesians 6:11). This armour defends the loins with truth, the vital organs with righteousness (Ephesians 6:14), the head with salvation (Ephesians 6:17), and the entirety with faith (Ephesians 6:16). The same armour provides the offensive weaponry in the word of God and prayer (Ephesians 6:17-18). Notice that the spiritual weaponry lacks any emphasis upon the physical.
The Bible clearly emphasizes that the Christian warfare is a “fight of faith” (1 Timothy 6:12) against spiritual foes (Ephesians 6:12). With this in mind, it only makes sense that the weapons used in this warfare would also be spiritual in nature. The Christian’s fight needs no physical arms, swords, or weaponry of any kind, yet the weapons of this warfare are “mighty through God to the pulling down of strong holds.” Those religions (and cults) who use physical weaponry to convert others to their “faiths” have never done this at the Lord’s bidding or direction. The Christian faith never has nor ever will convert one single person through use of a physical sword or threat. Instead, God’s people are completely reliant upon the words of God and the God of those words.
The fact that the Bible describes the Christian life as the good “fight of faith” (1 Timothy 6:12) reveals that the believer’s warfare is spiritual and never fleshly. In like manner, the enemy lives within the spiritual realm and this battle cannot be seen with the eyes of flesh. The enemy does not simply reside in a country on the other side of the world. In fact, it is no person or people group on this earth. Believers are told that they do not wrestle “against flesh and blood.” Ultimately, the saints’ enemy is the Devil, but his minions include principalities, powers, the rulers of the darkness of this world, and spiritual wickedness in high places. This means that the saints should never look to flesh and blood (mere mortals) for the source of their frustrations or victories. The fight is one of faith; the enemy, the Devil and the Lord our spiritual Captain (Hebrews 2:10).
Our words should never be used by the Devil as weapons to destroy or discourage others. Any problem with our words reveals a problem with our heart: “out of the abundance of the heart the mouth speaketh” (Matthew 12:34). The mouth can exhibit good or bad and our actions reveal the heart of the problem when the Bible says, “out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies” (Matthew 15:19). This is why our words are not always profitable to those who hear them. Yet, God admonishes us to “let no corrupt communication proceed out of” our mouth. Believers are instead encouraged to make sure their words are “good to the use of edifying.” The saint of God should speak words that God can use to build up other saints in the faith.
The knowledge of something wrong helps a spiritual person avoid such activity. On the surface, one might fail to distinguish much of a difference between the fruit of knowledge and charity in today’s passage. Both evidently build up the believer. Yet, a closer look reveals the major difference. The Bible says that knowledge “puffeth up.” The idea is that knowledge makes one feel superior and can offer a false strength. Knowledge seems to do the same work as charity, but knowledge without the charity serves as a façade. Charity, however, offers real growth and stability. Unlike knowledge, charity edifieth. Charity not only builds up the believer but also those who associate with that believer. The only way to be edified and the only way to edify others involves seeking the Lord for pure, unadulterated charity.
